Code review request: 7152169 TEST_BUG: sun/security/tools/jarsigner/ec.sh occasionally fail due to keytool error on sparc

[Vincent Ryan]

Please review the following fix:

Webrev: http://cr.openjdk.java.net/~vinnie/7152169/webrev.00/
Bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7152169

For some ECC curves, the field size does not match the uncompressed
point length. Relaxed the check in ECParameters.decodePoint().

Thanks.
